Title Page: The use of Remote
Sensing in Akagera National Park in order to analyze the impact of
wildfires on savanna growth patterns by Anna Weldy
Background:
- Akagera National Park background/history
- Wildfires rage through the savanna ecosystem
- Burns reduce plant fuel making fire in the next year less likely/drastic
- Importance of fire in maintaining biodiversity
- Burns reduce plant fuel making fire in the next year less likely/drastic
- Ash from wildfire is rich in minerals, which attracts animals.
Objective:
- To analyze, through remote sensing, how wildfires effect vegetation growth patterns over a span of four decades.
- What can analysis of vegetation growth tell scientists about environment, climate..
Methods:
- Landsat Data
- TM was used (1984-present) because it has more bands and was therefore more practical for this analysis.
- ENVI
- Indices:
- NDVI, SAVI/MSAVI, NBR, dNBR
- Math/equations
Data/Images:
- Four images from four decades before fires
- SAVI/MSAVI computed for all four and compared
- NDVI??
- Use images after fires to explain changes over time
- dNBR shows that a fire occurred and the severity of the burn.
Results/Conclusion:
- What changes occurred over time, to what extent, how do we know...
Applications:
- Fire management
- Understanding change due to climate change/management
